Corticosteroids and peptic ulcer: meta-analysis of adverse events during steroid therapy

Gastroduodenal Ulceration in Small Animals: Part 1. Pathophysiology and Epidemiology

Gastroduodenal ulceration in small animals is a complex and important comorbidity that occurs when the physiological homeostasis of the gastrointestinal tract is disrupted secondary to administration of medications or the presence of local or systemic diseases. The aim of this article is to provide a comprehensive review of the veterinary literature regarding the pathophysiology, epidemiology, and risk factors associated with gastroduodenal ulceration in small animals. Pertinent concepts from the human literature will be integrated into the discussion. This article serves as an introduction to the second part of this series, which will review current evidence regarding the use of H2-receptor antagonists and proton pump inhibitors in small animals.

Effective and safe proton pump inhibitor therapy in acid-related diseases - A position paper addressing benefits and potential harms of acid suppression

BACKGROUND

The introduction of proton pump inhibitors (PPIs) into clinical practice has revolutionized the management of acid-related diseases. Studies in primary care and emergency settings suggest that PPIs are frequently prescribed for inappropriate indications or for indications where their use offers little benefit. Inappropriate PPI use is a matter of great concern, especially in the elderly, who are often affected by multiple comorbidities and are taking multiple medications, and are thus at an increased risk of long-term PPI-related adverse outcomes as well as drug-to-drug interactions. Herein, we aim to review the current literature on PPI use and develop a position paper addressing the benefits and potential harms of acid suppression with the purpose of providing evidence-based guidelines on the appropriate use of these medications.

METHODS

The topics, identified by a Scientific Committee, were assigned to experts selected by three Italian Scientific Societies, who independently performed a systematic search of the relevant literature using Medline/PubMed, Embase, and the Cochrane databases. Search outputs were distilled, paying more attention to systematic reviews and meta-analyses (where available) representing the best evidence. The draft prepared on each topic was circulated amongst all the members of the Scientific Committee. Each expert then provided her/his input to the writing, suggesting changes and the inclusion of new material and/or additional relevant references. The global recommendations were then thoroughly discussed in a specific meeting, refined with regard to both content and wording, and approved to obtain a summary of current evidence.

RESULTS

Twenty-five years after their introduction into clinical practice, PPIs remain the mainstay of the treatment of acid-related diseases, where their use in gastroesophageal reflux disease, eosinophilic esophagitis, Helicobacter pylori infection, peptic ulcer disease and bleeding as well as, and Zollinger-Ellison syndrome is appropriate. Prevention of gastroduodenal mucosal lesions (and symptoms) in patients taking non-steroidal anti-inflammatory drugs (NSAIDs) or antiplatelet therapies and carrying gastrointestinal risk factors also represents an appropriate indication. On the contrary, steroid use does not need any gastroprotection, unless combined with NSAID therapy. In dyspeptic patients with persisting symptoms, despite successful H. pylori eradication, short-term PPI treatment could be attempted. Finally, addition of PPIs to pancreatic enzyme replacement therapy in patients with refractory steatorrhea may be worthwhile.

CONCLUSIONS

Overall, PPIs are irreplaceable drugs in the management of acid-related diseases. However, PPI treatment, as any kind of drug therapy, is not without risk of adverse effects. The overall benefits of therapy and improvement in quality of life significantly outweigh potential harms in most patients, but those without clear clinical indication are only exposed to the risks of PPI prescription. Adhering with evidence-based guidelines represents the only rational approach to effective and safe PPI therapy. Please see related Commentary: doi: 10.1186/s12916-016-0724-1 .

Oral corticosteroids in the management of chronic rhinosinusitis with and without nasal polyps: Risks and benefits

BACKGROUND

Oral steroids are synthetic mimics of adrenal cortex hormones and are considered a staple in the management of chronic rhinosinusitis due to their anti-inflammatory effects. Despite their common use, many providers are not familiar with the potential risks of the drugs.

METHODS

Literature review.

RESULTS

An overview of the existing data on the risks of oral steroids is presented as well as a review of the malpractice lawsuits with regard to oral steroid use and a discussion of the data that support the use of oral steroids in patients with chronic rhinosinusitis with and those without nasal polyps.

CONCLUSION

It is essential for providers to be aware of the potential complications of a medication, the medical jurisprudence of the drugs, and the data that support their use.

Complications Associated With High-dose Corticosteroid Administration in Children With Spinal Cord Injury

BACKGROUND

Complications with high-dose steroid administration for spinal cord injury are documented in adult patients. Our purpose was to determine the incidence of early complications of this therapy in pediatric patients with spinal cord injuries.

METHODS

An IRB-approved retrospective review was performed for patients treated for spinal cord injury at a level 1 pediatric trauma center between 2003 and 2011. Demographic data, injury characteristics, and surgical interventions were documented. Complications were divided into 4 categories: infectious, gastrointestinal (GI), hyperglycemia/endocrine, and wound healing problems. Complication rates were compared using a Student's t test and Fischer's exact test.

RESULTS

Thirty-four spinal cord injury patients were identified. Twenty-three patients (mean age 6.6 y) in the treatment group received high-dose steroid treatment and 11 patients (mean age 8.4 y) did not and comprised the control group. No statistical difference was detected between the 2 groups regarding age, mechanism of injury, rate of surgical intervention, level of injury, and injury severity. Hyperglycemia was the most common complication and was present in all patients in both the treatment and control groups. The overall infection rate was 64% in the control group compared with 26% in the treatment (P<0.05). The control group demonstrated a significantly increased rate of respiratory tract infections [45% control vs. 9% treatment (P<0.05)]. No surgical patients developed a wound infection. One treatment group patient experienced a GI bleed.

CONCLUSIONS

This is the largest study evaluating the complications associated with high-dose steroid administration for spinal trauma in a pediatric population. Hyperglycemia was found in all spinal cord injury patients, regardless of steroid treatment. Paradoxically, infection rates were noted to be higher in the control group. GI and wound problems were not significantly different. Larger, multicenter prospective studies are needed to better understand the risks in pediatric SCI patients.

Corticosteroids for treating nerve damage in leprosy

BACKGROUND

Leprosy causes nerve damage that can result in nerve function impairment and disability. Corticosteroids are commonly used for treating nerve damage, although their long-term effect is uncertain. This is an update of a review first published in 2007, and previously updated in 2009 and 2011.

OBJECTIVES

To assess the effects of corticosteroids on nerve damage in leprosy.

SEARCH METHODS

On 16 June 2015, we searched the Cochrane Neuromuscular Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL Plus, and LILACS. We also checked clinical trials registers and contacted trial authors.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs of corticosteroids for nerve damage in leprosy. The comparators were no treatment, placebo treatment, or a different corticosteroid regimen.

DATA COLLECTION AND ANALYSIS

The primary outcome was improvement in nerve function after one year. Secondary outcomes were change in nerve pain, limitations in activities of daily living, limitations in participation, and adverse events. Two review authors independently extracted data and assessed trial quality. When data were lacking, we contacted trial authors for additional information.

MAIN RESULTS

We included five RCTs involving 576 people. The trials were largely at low risk of bias, but we considered the quality of the evidence from these trials as moderate to low, largely due to imprecision from small sample sizes. Two out of the five trials reported on improvement in nerve function at one year. These two trials compared prednisolone with placebo. One trial, with 84 participants, treated mild sensory impairment of less than six months' duration, and the other, with 95 participants, treated nerve function impairment of 6 to 24 months' duration. There was no significant difference in nerve function improvement after 12 months between people treated with prednisolone and those treated with placebo. Adverse events were not reported significantly more often with corticosteroids than with placebo. The other three trials did not report on the primary outcome measure. One (334 participants) compared three corticosteroid regimens for severe type 1 reactions. No serious side effects of steroids were reported in any participant during the follow-up period. Another trial (21 participants) compared low-dose prednisone with high-dose prednisone for ulnar neuropathy. Two participants on the higher dose of prednisone reported adverse effects. The last (42 participants) compared intravenous methylprednisolone and oral prednisolone with intravenous normal saline and oral prednisolone. The trial found no significant differences between the groups in the occurrence of adverse events.

AUTHORS' CONCLUSIONS

Corticosteroids are used for treating acute nerve damage in leprosy, but moderate-quality evidence from two RCTs treating either longstanding or mild nerve function impairment did not show corticosteroids to have a superior effect to placebo on nerve function improvement. A third trial showed significant benefit from a five-month steroid regimen over a three-month regimen in terms of response to treatment (need for additional corticosteroids). Further RCTs are needed to establish optimal corticosteroid regimens and to examine the efficacy and safety of adjuvant or new therapies for treating nerve damage in leprosy. Future trials should address non-clinical aspects, such as costs and impact on quality of life, which are highly relevant indicators for both policymakers and participants.

Does Immunosuppressive Therapy Improve Outcomes in Graves' Disease? A Systematic Review and Meta-Analysis

BACKGROUND

Whether the addition of immunosuppressive drugs to standard antithyroid drugs reduces the relapse risk in Graves' disease remains uncertain.

PURPOSE

The aim of this study was to investigate the effects of immunosuppressive drugs on the relapse rate after a first episode of hyperthyroidism due to Graves' disease.

METHODS

Based on a pre-specified protocol, PubMed (1946-July 2015), EMBASE (1947-July 2015), and Cochrane (1992-July 2015) databases were searched. The search was for (randomized) controlled trials comparing immunosuppressive drugs with a control group. PRISMA and SIGN statements were used for assessing data quality. Two reviewers extracted data, with any disagreement being resolved by consensus. Data were pooled using a random-effects model.

RESULTS

The primary endpoint was relapse of disease until follow-up. Secondary endpoints included reduction of thyroid volume and decrease in thyrotropin-receptor antibody (TRAb) levels. Seven trials with 862 participants were included. Most trials were small with a moderate to high risk of bias. There were 113 relapses in 481 (23.5%) patients receiving immunosuppressive drugs compared with 225 relapses in 381 (59.1%) control patients (risk ratio for recurrence 0.55; [confidence interval (CI) 0.41-0.75]). Subgroup analyses showed similar effects for randomized trials and controlled trials (I(2) 0%), and for trials using corticosteroid and non-corticosteroid immunosuppressive drugs (I(2) 0%). Use of immunosuppressive drugs also resulted in significant reductions in thyroid volume (-10.72 mL [CI -15.59 to -5.85]) and TRAb levels (-17.01 IU/L [CI -33.31 to -0.72]). Immunosuppressive drug-related adverse effects were not systematically reported, and thus were not included in the quantitative analysis.

CONCLUSIONS

Current evidence suggests a possible relevant reduction in relapse risk when immunosuppressive drugs are added to standard treatment of Graves' disease. The small number of trials with high heterogeneity in regard to treatment modalities and the lack of systematic reporting of adverse effects calls for larger, conclusive trials.

Long-term side effects of glucocorticoids

INTRODUCTION

Glucocorticoids represent the standard therapy for reducing inflammation and immune activation in various diseases. However, as with any potent medication, they are not without side effects. Glucocorticoid-associated side effects may involve most major organ systems. Musculoskeletal, gastrointestinal, cardiovascular, endocrine, neuropsychiatric, dermatologic, ocular, and immunologic side effects are all possible.

AREAS COVERED

This article analyzes English-language literature and provides an update on the most recent literature regarding side effects of systemic glucocorticoid treatment.

EXPERT OPINION

The risk/benefit ratio of glucocorticoid therapy can be improved by proper use. Careful monitoring and using appropriate preventive strategies can potentially minimize side effects.

Symptomatic marginal ulcer disease after Roux-en-Y gastric bypass: incidence, risk factors and management

BACKGROUND

One of the long-term complications of laparoscopic Roux-and-Y gastric bypass (LRYGB) is the development of marginal ulcers (MU). The aim of the present study is to assess the incidence, risk factors, symptomatology and management of patients with symptomatic MU after LRYGB surgery.

METHODS

A consecutive series of patients who underwent a LRYGB from 2006 until 2011 were evaluated in this study. Signs of abdominal pain, pyrosis, nausea or other symptoms of ulcer disease were analysed. Acute symptoms of (perforated) MU such as severe abdominal pain, vomiting, melena and haematemesis were also collected. Patient baseline characteristics, medication and intoxications were recorded. Statistical analysis was performed to identify risk factors associated with MU.

RESULTS

A total of 350 patients underwent a LRYGB. Minimal follow-up was 24 months. Twenty-three patients (6.6%) developed a symptomatic MU of which four (1.1%) presented with perforation. Smoking, the use of corticosteroids and non-steroidal anti-inflammatory drugs (NSAIDs) was significantly associated with the development of MU. Five out of 23 patients (22%) underwent surgery. All other patients could be treated conservatively.

CONCLUSIONS

Marginal ulcers occurred in 6.6% of the patients after a LRYGB. Smoking, the use of corticosteroids and the use of NSAIDs were associated with an increased risk of MU. Most patients were managed conservatively.

Peptic ulcer disease in endogenous hypercortisolism: myth or reality?

Many clinicians believe hypercortisolism is ulcerogenic. However, data from clinical studies show that prophylaxis for peptic ulcer disease is no longer recommended in patients receiving corticosteroid treatment. This has not yet been verified in endogenous hypercortisolism by controlled clinical studies. The purpose of the current study was to evaluate the relationship between endogenous Cushing's syndrome (CS) and peptic ulcer disease and Helicobacter pylori infection. The study group contained 20 cases with CS resulting from ACTH-dependent endogenous hypercortisolism. The control groups consisted of 14 age- and gender-matched cases receiving exogenous corticosteroid therapy and 100 cases of dyspepsia with non-cushingoid features. Upper gastrointestinal endoscopy was performed on all cases. Biopsies were taken from five different points: two samples from the antrum, two samples from the corpus, and one sample from the fundus. A histological diagnosis of Helicobacter pylori infection was also obtained from evaluation of biopsy specimens. The frequency of stomach and duodenal ulcers did not vary between the groups (p = 0.5 and p = 0.7). Antral gastritis was less frequent and pangastritis was more common in cases with CS compared to the healthy controls (p = 0.001 and p < 0.001). The incidence of Candida esophagitis was more frequent in cases with CS compared to cases with corticosteroid treatment and healthy controls (p = 0.03). Histopathological findings and frequency of Helicobacter pylori based on pathology results did not vary between the three groups. It is possible that neither exogenous nor endogenous corticosteroid excess directly causes peptic ulcer or Helicobacter pylori infection. Prophylactic use of proton pump inhibitors is not compulsory for hypercortisolism of any type.

A case of bleeding duodenal ulcer with pemphigus vulgaris during steroid therapy

We report a rare case of bleeding duodenal ulceration in the different form of pemphigus vulgaris (PV). A 52-year-old female was diagnosed with acute pharyngitis and administered methylprednisolone. After several days, melena and many blisters were noted on her body. Endoscopy revealed blood oozing from the second part of a duodeneal ulcer around the major duodenal papilla. After initial endoscopic hemostasis, we observed a large regional, shallow duodenal ulcer. The blisters were suspected to represent the Nikolsky's sign. The histological findings of her skin were characterized by suprabasal acantholysis and mixed inflammatory cell infiltrates, including scattered eosinophils. There were no other significant findings on skin biopsy or by direct immunofluorescence. Enzyme-linked immunosorbent assay showed an elevated titer of anti-desmoglein 3 autoantibodies in her serum, and the patient was finally diagnosed with mucosal-dominant PV. Although we performed multiple biopsies from the esophagus, stomach and duodenum, the samples did not contain significant findings to enable us to distinguish from pemphigus vulgaris. Corticosteroids remain an essential component of PV treatment. When clinicians encounter PV development during steroid therapy, upper gastrointestinal complications should be considered and diagnostic endoscopy conducted.

Medical management of brain tumors and the sequelae of treatment

Patients with malignant brain tumors are prone to complications that negatively impact their quality of life and sometimes their overall survival as well. Tumors may directly provoke seizures, hypercoagulable states with resultant venous thromboembolism, and mood and cognitive disorders. Antitumor treatments and supportive therapies also produce side effects. In this review, we discuss major aspects of supportive care for patients with malignant brain tumors, with particular attention to management of seizures, venous thromboembolism, corticosteroids and their complications, chemotherapy including bevacizumab, and fatigue, mood, and cognitive dysfunction.

Monitoring of patients on long-term glucocorticoid therapy: a population-based cohort study

About 1% of the general population receives long-term systemic glucocorticoids. The monitoring provided to these patients is unknown. We conducted a population-based cohort study using The Health Improvement Network database. A total of 100,944 adult patients prescribed systemic glucocorticoids for >3 months between January 2000 and December 2012 were studied. The monitoring done before prescribing glucocorticoid therapy and during exposure to the drug was examined. This included measurement of body weight, blood pressure, lipids, glucose and potassium levels, referrals for dual-energy X-ray absorptiometry (DEXA-scan) or to an ophthalmologist/optician, and vaccinations. We assessed factors associated with the odds of being monitored before and during exposure. Before glucocorticoid initiation, weight and blood pressure were monitored in < 20% and < 50% of patients, respectively. Glucose and lipid levels were monitored in less than one-third of the patients, while DEXA-scan and eye monitoring were offered to <15% of them. Vaccination against flu and pneumococcus was given to 57% and 46% of the patients, respectively. During exposure to the drug, <60% of patients who were prescribed the drug for more than a year had their weight, glucose, or lipid levels recorded at least once and <25% of patients were referred at least once for DEXA-scan or screening for eye diseases. Overall, the odds of being monitored were higher in older patients and in those with comorbidities. There were variations in the level of monitoring provided across the UK, but the monitoring has improved over the last 12 years. Although the extent of monitoring of people on long-term glucocorticoids has improved over time, the overall monitoring provided is not satisfactory, particularly in young patients and those without comorbidities.

A case of glucocorticoid-induced diabetes in which the efficacy between sitagliptin and metformin was compared

To date, promising strategies for treating glucocorticoid (GC)-induced diabetes with antidiabetic drugs have not been established. We herein report the case of a woman with GC-induced diabetes in which we compared the efficacy of two kinds of orally administered antidiabetic drugs sitagliptin and metformin by continuous glucose monitoring (CGM) and meal-challenge test (MCT). As a result, CGM showed that daily fluctuation of blood glucose levels was reduced during administration of metformin but not during administration of sitagliptin. On the other hand, MCT showed that administration of metformin reduced plasma glucose levels accompanied by the decrease of plasma insulin levels and the increase of plasma glucagon levels, whereas administration of sitagliptin had little effects on these parameters. This case is the first report to compare the efficacy between sitagliptin and metformin in glucose homeostasis by CGM and MCT in a patient with GC-induced diabetes.

The safety of low-dose glucocorticoids in rheumatic diseases: results from observational studies

Glucocorticoids (GC) remain the most commonly used agents for managing inflammatory rheumatic diseases. The adverse effects (AEs) associated with high-dose GCs are well established, but there is a widespread misconception that AEs of high-dose GC therapy (>30 mg of prednisone or equivalent daily) are similar in low-dose therapy (≤7.5 mg of prednisone equivalent a day). Although high-quality evidence on AEs of low-dose GC therapy is still incomplete, risks and safety of low-dose GC therapy in rheumatic diseases are reviewed based on current evidence by category, including musculoskeletal, cardiovascular, infectious, gastrointestinal, neuropsychiatric, endocrine and metabolic, dermatologic, and ophthalmologic AEs. Recommendations concerning monitoring AEs with low-dose GC therapy are provided for each category of AEs on the basis of our literature review and clinical experience. There is emerging evidence that low-dose GCs are associated with a much lower level of AEs, which would allow their use over long periods in patients with rheumatic disease who gain clinical effectiveness and well-being from their use. Nonetheless, knowledge and understanding of AEs from low-dose GCs is vital to maximize benefits and minimize risks to patients.

Bolus administration of steroid therapy is more favorable than the conventional use in preventing decrease of bone density and the increase of body fat percentage in patients with inflammatory bowel disease

INTRODUCTION

The effects of short course of corticosteroids on the metabolic processes and bone formation has not been well studied. Our aim was to compare the efficacy, the side effects and the bone and lipid metabolisms in IBD patients using bolus or conventional tapering of methylprednisolone for 12 weeks.

PATIENTS AND METHODS

Nineteen IBD patients received intravenous methylprednisolone of 1mg/kg for 5 days tapered by 4 mg per week. Patients were prospectively randomized in two groups. In "conventional" group (I) steroids were given daily. In "pulse" group (II) weekly doses of steroids were given on special days of the week. The body mass index (BMI) was measured before and after the corticosteroid therapy. Blood samples were collected to assess glucose level, electrolytes, cholesterol and triglyceride levels, inflammatory parameters, cortisol, osteocalcin and crosslaps values. Total body composition analysis was performed at the beginning and at the end of the steroid therapy.

RESULTS

In Group I, BMI increased, total body bone density decreased significantly at the end of the steroid therapy. Body fat percent showed a tendency to be higher at the end of steroid therapy in Group I. Cholesterol level increased significantly in Group I patients. The decrease in serum cortisol level was more remarkable in Group I vs. Group II after steroid therapy. Less side-effect occurred in Group II vs. Group I.

DISCUSSION

Our results suggest that bolus tapering of corticosteroids may have more favorable short term outcome than conventional tapering that may revolutionize steroid therapy in IBD.

Use of dexamethasone in patients with high-grade glioma: a clinical practice guideline

BACKGROUND

Dexamethasone is the corticosteroid most commonly used for the management of vasogenic edema and increased intracranial pressure in patients with brain tumours. It is also used after surgery (before embarking on radiotherapy), particularly in patients whose tumours exert significant mass effect. Few prospective clinical trials have set out to determine the optimal dose and schedule for dexamethasone in patients with primary brain tumours, and subsequently, fewer clinical practice guideline recommendations have been formulated.

METHODS

A review of the scientific literature published to November 2012 considered all publications that addressed dexamethasone use in adult patients with brain tumours. Evidence was selected and reviewed by a working group comprising 3 clinicians and 1 methodologist. The resulting draft guideline underwent internal review by members of the Alberta Provincial cns Tumour Team, and feedback was incorporated into the final version of the guideline.

RECOMMENDATIONS

Based on the evidence available to date, the Alberta Provincial cns Tumour Team makes these recommendations: Treatment with dexamethasone is recommended for symptom relief in adult patients with primary high-grade glioma and cerebral edema.After surgery, a maximum dose of 16 mg daily, administered in 4 equal doses, is recommended for symptomatic patients. This protocol should ideally be started by the neurosurgeon.A rapid dexamethasone tapering schedule should be considered where appropriate.Patients who have high-grade tumours, are symptomatic, or have poor life expectancy, can be maintained on a 0.5-1.0 mg dose of dexamethasone daily.Side effects with dexamethasone are common, and they increase in frequency and severity with increased dose and duration of therapy. Patients should be carefully monitored for endocrine, muscular, skeletal, gastrointestinal, psychiatric, and hematologic complications, and for infections and other general side effects.

Corticosteroids and risk of gastrointestinal bleeding: a systematic review and meta-analysis

OBJECTIVE

To assess whether corticosteroids are associated with increased risk of gastrointestinal bleeding or perforation.

DESIGN

Systematic review and meta-analysis of randomised, double-blind, controlled trials comparing a corticosteroid to placebo for any medical condition or in healthy participants. Studies with steroids given either locally, as a single dose, or in crossover studies were excluded.

DATA SOURCES

Literature search using MEDLINE, EMBASE and Cochrane Database of Systematic Reviews between 1983 and 22 May 2013.

OUTCOME MEASURE

Outcome measures were the occurrence of gastrointestinal bleeding or perforation. Predefined subgroup analyses were carried out for disease severity, use of non-steroidal anti-inflammatory drugs (NSAIDs) or gastroprotective drugs, and history of peptic ulcer.

RESULTS

159 studies (N=33 253) were included. In total, 804 (2.4%) patients had a gastrointestinal bleeding or perforation (2.9% and 2.0% for corticosteroids and placebo). Corticosteroids increased the risk of gastrointestinal bleeding or perforation by 40% (OR 1.43, 95% CI 1.22 to 1.66). The risk was increased for hospitalised patients (OR 1.42, 95% CI 1.22 to 1.66). For patients in ambulatory care, the increased risk was not statistically significant (OR 1.63, 95% CI 0.42 to 6.34). Only 11 gastrointestinal bleeds or perforations occurred among 8651 patients in ambulatory care (0.13%). Increased risk was still present in subgroup analyses (studies with NSAID use excluded; OR 1.44, 95% CI 1.20 to 1.71, peptic ulcer as an exclusion criterion excluded; OR 1.47, 95% CI 1.21 to 1.78, and use of gastroprotective drugs excluded; OR 1.42, 95% CI 1.21 to 1.67).

CONCLUSIONS

Corticosteroid use was associated with increased risk of gastrointestinal bleeding and perforation. The increased risk was statistically significant for hospitalised patients only. For patients in ambulatory care, the total occurrence of bleeding or perforation was very low, and the increased risk was not statistically significant.

Atherosclerosis in systemic lupus erythematosus

Accelerated atherosclerosis and its long-term sequelae are a major cause of late mortality among patients with systemic lupus erythematosus (SLE). Traditional Framingham risk factors such as hypertension, hypercholesterolemia, diabetes, and smoking do not account in entirety for this risk. SLE specific factors like disease activity and duration, use of corticosteroids, presence of antiphospholipid antibodies, and others are important risk factors. SLE is considered a coronary heart disease; equivalent and aggressive management of all traditional risk factors is recommended. Despite their role in primary and secondary prevention in the general population, statins seem to have no effect on cardiovascular outcomes in adult or pediatric SLE populations. The use of hydroxychloroquine has a cardioprotective effect, and mycophenolate mofetil may reduce cardiovascular events based on basic science data and data from the transplant population. The role of vitamin D supplementation and treatment of hyperhomocysteinemia remain controversial, but due to the safety of therapy and the potential benefit, they remain as optional therapies.

Glucocorticoids: complications to anticipate and prevent

Glucocorticoids (GCs) are widely used for inflammatory and autoimmune diseases. Their mechanism of action is most commonly rooted in genomic effects that have both beneficial and adverse consequences. The purpose of this review is to discuss the potential complications and side effects that may occur with GC use. Many of these complications are related to the dose and duration of therapy used. Evidence-based preventative strategies are discussed. Many recommendations are based on expert opinion and not on strong evidence. A 54-year-old man presents with proximal upper and lower extremity weakness. There are no rashes. The antinuclear antibody is negative; the erythrocyte sedimentation rate and C reactive protein are 24 mm/h and 3 mg/dL, respectively. An electromyography displays myopathic motor unit potentials with fibrillation and a muscle biopsy confirms polymyositis. Prednisone of 60 mg/d is initiated. What are the risks associated with GC use? What other studies and interventions should occur in this patient starting long-term GC therapy?

A practical guide to the monitoring and management of the complications of systemic corticosteroid therapy

Systemic corticosteroids play an integral role in the management of many inflammatory and immunologic conditions, but these agents are also associated with serious risks. Osteoporosis, adrenal suppression, hyperglycemia, dyslipidemia, cardiovascular disease, Cushing’s syndrome, psychiatric disturbances and immunosuppression are among the more serious side effects noted with systemic corticosteroid therapy, particularly when used at high doses for prolonged periods. This comprehensive article reviews these adverse events and provides practical recommendations for their prevention and management based on both current literature and the clinical experience of the authors.

Physicians' opinions of stress ulcer prophylaxis: survey results from a large urban medical center

BACKGROUND

Stress ulcer prophylaxis (SUP) has been increasingly prescribed for patients admitted to medical wards. The knowledge, attitudes, and practices of those in the healthcare profession regarding use of SUP in medical wards are understudied.

METHODS

A survey consisting of closed-ended questions and multiple-choice queries was handed out during grand rounds.

RESULTS

One hundred people (39 attending physicians, 61 residents) completed the survey. More attending physicians (41 vs. 30 %) believed SUP was indicated for patients treated in a non-intensive-care medical ward (P = 0.2357). All residents preferred a proton-pump inhibitor (PPI) for SUP compared with 85 % of attending physicians (P < 0.05). Despite equal agreement that PPIs were not harmless, more attending physicians than residents agreed that using PPIs increased the risk of community-acquired pneumonia (P < 0.05). More residents than attending physicians agreed on the use of SUP for patients suffering from major burns and for those with liver failure. In situations of respiratory distress not requiring intubation and in cases of steroid treatment for a chronic obstructive pulmonary disease flare, more attending physicians than residents felt SUP was required. Approaching a statistically significant difference, more attending physicians than residents felt that being too busy to question SUP indication and the perception of PPIs as harmless affected decision making.

CONCLUSION

Despite the publication of guidelines, misuse of gastric acid suppressants continues to occur, even by attending physicians. More complete understanding of the need and occasion for SUP use should result in more cautious use.

[Systemic glucocorticoid therapy: associated measures]

Long-term treatment with glucocorticoids results in many adverse effects. Prevention of osteoporosis is well codified, but prevention of other adverse effects is not. If there is some consensus on the prevention of glucocorticoid-induced adverse events, there are also many habits since interventional studies are lacking. A low caloric and low carbohydrate diet as well as a regular physical training are certainly necessary to avoid lipodystrophy, weight gain and diabetes mellitus. Some patients benefit from the repeated intervention of a dietetic or nutrition specialist. Physical training is often neglected though it is efficacious to limit severity of glucocorticoid-induced myopathy and probably to reduce vascular risk. Low sodium intake has no effect on lipodystrophy and its efficacy to prevent hypertension is doubtful. Benzodiazepines may be useful against anxiety, insomnia and nervousness when these symptoms are cumbersome. Anti-ulcer drugs are generally not indicated because glucocorticoids are not ulcerogenic. Hypokaliemia rarely occurs, so we prefer controlling serum potassium level 1 and 3 months after glucocorticoid initiation rather than systematically prescribe potassium supplementation. Patients on glucocorticoids are at increased risk for cardiovascular events. Due to the lack of studies specific to patients on long-term glucocorticoid therapy, the rules for the prescription of statins are the same as in the general population. There is no known prevention for cutaneous atrophy. However, use of adhesive tape should be strictly avoided when skin atrophy is severe. Prevention of infections is developed elsewhere.

Successful use of mRNA-nucleofection for overexpression of interleukin-10 in murine monocytes/macrophages for anti-inflammatory therapy in a murine model of autoimmune myocarditis

Background

Overexpression of interleukin-10 (IL-10) in murine CD11b⁺ monocytes/macrophages via GMP-adapted mRNA-nucleofection was expected to improve clinical outcome and reduce adverse side effects in autoimmune myocarditis. This study represents the proof of principle for a novel anti-inflammatory therapy using overexpression of IL-10 in murine monocytes/macrophages by mRNA-nucleofection for the treatment of autoimmune myocarditis.

Methods and Results

Autoimmune myocarditis was induced in A/J mice by subcutaneous immunization with troponin I. CD11b⁺ monocytes/macrophages were isolated from the peritoneum and IL-10 was overexpressed by mRNA-nucleofection. These cells were injected intravenously. Myocardial inflammation was assessed via histological and immunohistochemical examinations. Myocardial fibrosis was analyzed with Masson's trichrome staining. Antitroponin I antibodies were determined within the serum. Physical performance was evaluated using a running wheel and echocardiography. In vitro overexpression of IL-10 in CD11b⁺ monocytes/macrophages resulted in a 7-fold increased production of IL-10 (n=3). In vivo higher levels of IL-10 and less inflammation were detected within the myocardium of treated compared with control mice (n=4). IL-10–treated mice showed lower antitroponin I antibodies (n=10) and a better physical performance (n=10).

Conclusions

Application of IL-10–overexpressing CD11b⁺ monocytes/macrophages reduced inflammation and improved physical performance in a murine model of autoimmune myocarditis. Thus, the use of genetically modified monocytes/macrophages facilitated a targeted therapy of local inflammation and may reduce systemic side effects. Because the nucleofection technique is GMP adapted, an in vivo use in humans seems basically feasible and the transfer to other inflammatory diseases seems likely.

Two randomized controlled clinical trials to study the effectiveness of prednisolone treatment in preventing and restoring clinical nerve function loss in leprosy: the TENLEP study protocols

Background

Nerve damage in leprosy often causes disabilities and deformities. Prednisolone is used to treat nerve function impairment (NFI). However, optimal dose and duration of prednisolone treatment has not been established yet. Besides treating existing NFI it would be desirable to prevent NFI. Studies show that before NFI is clinically detectable, nerves often show subclinical damage. Within the ‘Treatment of Early Neuropathy in LEProsy’ (TENLEP) study two double blind randomized controlled trials (RCT) will be carried out: a trial to establish whether prednisolone treatment of 32 weeks duration is more effective than 20 weeks in restoring nerve function in leprosy patients with clinical NFI (Clinical trial) and a trial to determine whether prednisolone treatment of early sub-clinical NFI can prevent clinical NFI (Subclinical trial).

Methods

Two RCTs with a follow up of 18 months will be conducted in six centers in Asia. In the Clinical trial leprosy patients with recent (< 6 months) clinical NFI, as determined by Monofilament Test and Voluntary Muscle Test, are included. The primary outcomes are the proportion of patients with restored or improved nerve function. In the Subclinical trial leprosy patients with subclinical neuropathy, as determined by Nerve Conduction Studies (NCS) and/or Warm Detection Threshold (WDT), and without any clinical signs of NFI are randomly allocated to a placebo group or treatment group receiving 20 weeks prednisolone. The primary outcome is the proportion of patients developing clinical NFI. Reliability and normative studies are carried out before the start of the trial.

Discussion

This study is the first RCT testing a prednisolone regimen with a duration longer than 24 weeks. Also it is the first RCT assessing the effect of prednisolone in the prevention of clinical NFI in patients with established subclinical neuropathy. The TENLEP study will add to the current understanding of neuropathy due to leprosy and provide insight in the effectiveness of prednisolone on the prevention and recovery of NFI in leprosy patients. In this paper we present the research protocols for both Clinical and Subclinical trials and discuss the possible findings and implications.

Variables associated with stress ulcer prophylaxis misuse: a retrospective analysis

BACKGROUND

Stress ulcer prophylaxis (SUP) is commonly used in hospitals. Although its indications are better delineated for intensive care unit (ICU) patients, its use in non-ICU settings is somewhat arbitrary and based on judgment.

OBJECTIVE

We attempted to assess the extent of SUP overuse in our hospital. We also carefully collected and analyzed several variables to detect associations governing this flawed behavior and its financial burden on the hospital's budget.

MATERIALS AND METHODS

We retrospectively analyzed charts of patients admitted to the medical floor of a tertiary referral university hospital over a 1 year period. All adult patients admitted to the medical ward who received at least one dose of SUP were included and reviewed for a multitude of variables in addition to the appropriateness of acid suppression therapy (AST).

RESULTS

We included 320 charts and found that 92% of patients admitted during that period were not eligible for SUP. The total inappropriateness of SUP was noted to be 58% (p = 0.015). Increasing age and male gender were found to be significant variables in AST misuse (p = 0.045 and p = 0.010), much like duration of hospital stay (p = 0.008). Comorbidities was also found to be a defining variable for AST overuse (odds ratio [OR] = 3.27). Patients with two or more minor risk factors were also subjected more to SUP inappropriately (OR = 3.53), in addition to patients of certain specialties (Neurology, Infectious Diseases, etc.). Our calculated financial burden was more than $23,000 per year for the medical floor.

CONCLUSION

This retrospective study confirmed the growing suspicion that SUP misuse is evident on the medical floors. We also delineated several factors and variables associated with and affecting SUP overuse.

Factors associated with the initiation of proton pump inhibitors in corticosteroid users

PURPOSE

Proton pump inhibitors (PPIs) and corticosteroids are commonly prescribed drugs; however, each has been associated with fracture and community-acquired pneumonia. How physicians select patients for co-therapy may have implications for potential additive or synergistic toxicities.

METHODS

We conducted a retrospective cohort study of 13 749 incident corticosteroid users with no prior PPI exposure using the HealthCore Integrated Research Database(SM) . We used logistic regression to evaluate the association between PPI initiation in the first 30 days of steroid therapy and corticosteroid dose, clinical risk factors including comorbid diseases, and medication use including prescription nonsteroidal anti-inflammatory drugs (NSAIDs).

RESULTS

A new PPI prescription within 30 days of starting corticosteroids was filled by 1050 patients (7.6%). PPI use was associated with the number of baseline comorbid conditions (OR = 1.21 for each additional condition, 95%CI = 1.13-1.28), recent hospitalization (OR = 4.71, 95%CI = 4.02-5.52), prednisone dose higher than 40 mg/day (OR = 1.87, 95%CI = 1.45-2.41), history of gastroesophageal reflux or gastric ulcer disease (OR = 1.54, 95%CI = 1.24-1.91), renal insufficiency (OR = 2.06, 95%CI = 1.73-2.46), and liver disease (OR = 1.82, 95%CI = 1.45-2.28). The concomitant use of prescription NSAIDs was also associated with PPI use (OR = 1.89, 95%CI = 1.32-2.70); however, the total use of PPIs in this group was low (6.3%, 95%CI = 4.4-8.2%).

CONCLUSIONS

Overall, PPI therapy among corticosteroid users was uncommon, even among those with risk factors for gastrointestinal toxicity. PPI use was significantly more common among patients who had recently been hospitalized, had a greater burden of comorbid illness, or were receiving high daily doses of corticosteroids.

Evaluation of weekly-reduction regimen of glucocorticoids in combination with cyclophosphamide for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis in Japanese patients

The current therapeutic regimen recommended by the European League against Rheumatism (EULAR) for anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV) is continuation of initially administered doses of glucocorticoids (GCs) in combination with cyclophosphamide (CYC) for 1 month followed by gradual tapering. Considering the adverse effects of GCs, another tapering regimen of GCs with CYC, which was characterized by tapering GCs weekly, was reported by the British Society of Rheumatology (weekly-reduction regimen). The aim of the present study is to evaluate the safety and efficacy of this weekly-reduction regimen for Japanese AAV patients in comparison with the monthly-reduction regimen recommended by the EULAR. We retrospectively reviewed medical records of adult patients newly diagnosed with AAV during the period from April 2000 to December 2010. The outcome measures were rates of remission, relapse, infection, and GC-induced diabetes mellitus during the first 12 months. Clinical data in the two groups and categorial variables with a possible relation to the outcomes were compared by using the t test and chi-square test, respectively. Twenty-four patients were enrolled in our study. All of the patients achieved remission, and the rates of relapse during the first 12 months were not statistically different between the two groups (P = 0.16). Patients treated with the weekly-reduction regimen were less liable to have infection (P = 0.03) and impaired glucose tolerance (P = 0.017), compared with those treated with the monthly-reduction regimen. A therapeutic strategy using the weekly-reduction regimen of GCs would be effective and would have fewer side effects than the monthly-reduction regimen.

Duodenal perforation in a patient with non-small cell lung cancer receiving Pemetrexed-Cisplatin combination

Pemetrexed is increasingly used in combination with platinum antineoplastic agents for the treatment of certain lung malignancies. Its use was associated with favorable hematological adverse reaction compared to standard regimens. Non-hematological life-threatening complications such as gastrointestinal perforations are extremely rare with pemetrexed use and tend to develop in the distal bowel in patients at risk.

We report the case of a 56-years old Arab male, heavy smoker newly diagnosed with Stage IV non-small cell lung cancer with no comorbidities, treated with pemetrexed-cisplatin combination. Four days after the first cycle of chemotherapy, the patient developed a small duodenal perforation that required emergency laparoscopy repair.

Clinicians should have a high index of suspicion should be taken for alimentary tract perforation in patients presenting with acute abdominal pain during pemetrexed therapy.

Glucocorticoids and gastric mucosal lesions

Hench found glucocorticoids (GCs), defined their roles in controlling rheumatic diseases, and thereby won the 1950 Nobel Prize in physiology and medicine. In the next few decades GCs were widely used in clinical practice; however, they were associated with some side effects, such as gastric mucosal lesions. Currently, it is still controversial whether GC use is a risk factor for peptic ulcer disease and upper gastroduodenal bleeding. This review aims to elucidate the potential role of GCs in inducing gastric mucosal lesions and to highlight possible mechanisms involved.

Increased incidence of pre-diabetes mellitus at a department of rheumatology: a retrospective study

We aimed to retrospectively review the incidence of pre-diabetes mellitus (preDM), one of the factors in metabolic syndrome screening, in patients with rheumatic diseases. We examined the levels of hemoglobin A1c (HbA1c) in a total of 498 patients with rheumatic diseases between April 2007 and March 2008 at the Department of Rheumatology in Nagasaki University Hospital. Of the 498 patients, 409 (82.1%) had HbA1c levels higher than 5.6% (National Glycohemoglobin Standardization Program; NGSP) and were recommended for health guidance with a focus on metabolic syndrome. Serum HbA1c levels higher than 6.0%, a possible indicator of DM, were seen in 227 patients (45.6%). Serum HbA1c levels higher than 6.5%, which constitute a high risk for DM, were found in 115 patients (23.1%). PreDM increased gradually with age. Our results suggest that the incidence of preDM may be higher in patients with rheumatic diseases than in patients with other diseases and that these patients should receive healthcare guidance to prevent metabolic syndrome.

Impact of glucocorticoid-induced adverse events on adherence in patients receiving long-term systemic glucocorticoid therapy

BACKGROUND

Factors influencing adherence to long-term (i.e. ≥ 3 months) systemic glucocorticoid therapy are poorly understood.

OBJECTIVE

To evaluate the relationship between glucocorticoid-induced adverse events and therapeutic adherence in patients on long-term glucocorticoid treatment.

METHODS

A cross-sectional survey was conducted in three departments of dermatology/internal medicine between April and September 2008. Patients were asked to provide data regarding symptoms they attributed to glucocorticoids, and adherence to treatment was measured using the four-item Morisky-Green adherence scale. Logistic regression analyses were used to assess the association between reported adverse events and adherence to glucocorticoids.

RESULTS

A total of 255 questionnaires were completed and analysed [women 78%; median age 48 years (interquartile range (IQR) 34-65); connective tissue diseases 59%; median duration of treatment 24 months (IQR 8-72); median daily dose 10 mg (IQR 6-20)]. Among these 255 patients, 199 (78%) reported themselves as 'good adherents' and 56 (22%) as 'poor adherents' to treatment. Poor adherence was associated with younger age [odds ratio (OR) 0·97, 95% confidence interval (CI) 0·95-0·99, per increasing year; P < 0·01], presence of glucocorticoid-induced epigastralgia (OR 4·02, 95% CI 2·00-8·09; P < 0·01) and presence of glucocorticoid-induced morphological changes (OR 2·49, 95% CI 1·19-5·21; P = 0·02). Moreover, patients with poor adherence were likely to report concomitantly poor adherence to dietary advice associated with glucocorticoid therapy (OR 2·44, 95% CI 1·12-5·26; P = 0·02).

CONCLUSIONS

As with other chronic therapies, the presence of glucocorticoid-induced adverse events is associated with an altered self-reported adherence to glucocorticoids. Patients who report epigastric pain or morphological changes that they associate with glucocorticoid therapy are particularly at risk of poor adherence. Adherence to dietary advice associated with glucocorticoid therapy may be an indirect measure of treatment adherence.
